- * Fixes browser bugs compared to the native `String.prototype.split` and can be used reliably

- * @param {String} str String to split.
- * @param {RegExp|String} separator Regex or string to use for separating the string.
- * @param {Number} [limit] Maximum number of items to include in the result array.
- * @returns {Array} Array of substrings.
- * @example
- *
- * // Basic use
- * split('a b c d', ' ');
- * // -> ['a', 'b', 'c', 'd']
- *
- * // With limit
- * split('a b c d', ' ', 2);
- * // -> ['a', 'b']
- *
- * // Backreferences in result array

- * Observable.

- * // will log a MouseEvent object to the console. If the result is less

- // interval period, regardless of load.

- * @class GeoCoords
- *
- * @classdesc Converts coordinates between the geodetic (WGS84),
- * Earth-Centered, Earth-Fixed (ECEF) and local topocentric
- * East, North, Up (ENU) reference frames.
- *
- * The WGS84 has latitude (degrees), longitude (degrees) and
- * altitude (meters) values.
- *
- * The ECEF Z-axis pierces the north pole and the
- * XY-axis defines the equatorial plane. The X-axis extends
- * from the geocenter to the intersection of the Equator and
- * the Greenwich Meridian. All values in meters.
- *
- * The WGS84 parameters are:
- *
- * a = 6378137
- * b = a * (1 - f)
- * f = 1 / 298.257223563
- * e = Math.sqrt((a^2 - b^2) / a^2)
- * e' = Math.sqrt((a^2 - b^2) / b^2)
- *
- * The WGS84 to ECEF conversion is performed using the following:
- *
- * X = (N - h) * cos(phi) * cos(lambda)
- * Y = (N + h) * cos(phi) * sin(lambda)
- * Z = (b^2 * N / a^2 + h) * sin(phi)
- *
- * where
- *
- * phi = latitude
- * lambda = longitude
- * h = height above ellipsoid (altitude)
- * N = Radius of curvature (meters)
- * = a / Math.sqrt(1 - e^2 * sin(phi)^2)
- *
- * The ECEF to WGS84 conversion is performed using the following:
- *
- * phi = arctan((Z + e'^2 * b * sin(theta)^3) / (p - e^2 * a * cos(theta)^3))
- * lambda = arctan(Y / X)
- * h = p / cos(phi) - N
- *
- * where
- *
- * p = Math.sqrt(X^2 + Y^2)
- * theta = arctan(Z * a / p * b)
- *
- * In the ENU reference frame the x-axis points to the
- * East, the y-axis to the North and the z-axis Up. All values
- * in meters.
- *
- * The ECEF to ENU conversion is performed using the following:
- *
- * | x | | -sin(lambda_r) cos(lambda_r) 0 | | X - X_r |
- * | y | = | -sin(phi_r) * cos(lambda_r) -sin(phi_r) * sin(lambda_r) cos(phi_r) | | Y - Y_r |
- * | z | | cos(phi_r) * cos(lambda_r) cos(phi_r) * sin(lambda_r) sin(phi_r) | | Z - Z_r |
- *
- * where
- *
- * phi_r = latitude of reference
- * lambda_r = longitude of reference
- * X_r, Y_r, Z_r = ECEF coordinates of reference
- *
- * The ENU to ECEF conversion is performed by solving the above equation for X, Y, Z.
- *
- * WGS84 to ENU and ENU to WGS84 are two step conversions with ECEF calculated in
- * the first step for both conversions.
